My most famous project is musictheory.net, which I launched in 2000 as a free resource for music education. In 2011, I resigned from my day job at Apple to focus on the site full time. We launched Tenuto and Theory Lessons later that year.

Mac Apps

While musictheory.net occupies most of my time, I also create and sell macOS applications
via Apple's Mac App Store. While
these were all originally quickly-made tools for personal use, I later decided to apply my
rigorous quality standards and release them to the world.

When Apple released Lion in 2011, many web developers and graphics professionals were shocked at the
dramatic reduction of DigitalColor Meter's functionality. As this personally affected my workflow, I challenged
myself to recreate the previous version from scratch. Classic Color Meter is the result of this challenge.
During its development, I had to conduct copious research into macOS ColorSync.

I often DJ for various social partner dance events. This is different from club DJing, and I wasn't able to
find a suitable music player that met all of my requirements. Hence, I created
Embrace in early 2014.

During development work, I often repeat the same process: capture a screenshot of my website/application,
open it in an image editor, and measure the pixel dimensions of a section of the screenshot.
Pixel Winch is my attempt to streamline this process.
